He used his hands to show that Arsenal were winning 2-0 and the FA are unlikely to take any action because the gesture was not offensive.

Television pictures show that Tottenham fans were already throwing coins, missiles and liquid even before Walcott reacted, and the FA are likely to study referee Mark Clattenburg before taking action against the supporters or Spurs.

Walcott received support from his Arsenal team mate Jack Wilshere, who was hit with a two game ban for making an obscene gesture at Manchester City.

Wilshere said: “I think they were giving him a bit of stick. He’s a bit smarter than me, I suppose! He’ll be an Arsenal legend now. That’s football.

“They were giving it to him and he’s given a little bit back. I think people have got to look at it as banter. The Arsenal fans will love that. They love Theo already and this is only going to help him.”
